Sylmar fire moving west -- fast

The fire is being pushed by winds past the 5 Freeway toward Porter Ranch, into an area burned by last month's Sesnon fire.

Evacuations now extend west to Reseda Boulevard. The L.A. Fire Department said 10,000 people in total had been ordered to evacuate. A mobile home park in Sylmar is on fire.

"The fire is ripping and tearing through everything," said the LAFD's Michael Bowman.

The path of the fire fits a common pattern for blazes driven by Santa Ana winds in the San Fernando Valley. The question: How far west will the fire go? The Sesnon blaze roared to Ventura County, and others have marched toward the 101 Freeway and even to Malibu. Others get stopped in their tracks.
